Entry title

Purpose: To create a large 20 g casting of 1% 2.08% by weight NH4+-CNC and contiune running the XRD samples.

Safety and Procedure: For the large scale casting 200 mL of acetone will be mixed with the mass of additive. For NH4+-CNC the solution of acetone and NH4+-CNC will be blended in a blender to assist in dispersing the additive and decrease the amount of time needed to sonicate. After the plastic is added and properly dispersed the solution will be poured into a metal frying pan to solidify. To assist in this the pan will be heated on a hot plate at 80°C for about two and a half hours until solid. See 6/13/14 for XRD procedure.

Experimental:

Ran the XRD on the two ABS and one PLA sample from 6/17/14.

Created a 20 g 1% NH4+-CNC casting

Mass % Mass NH4+-CNC Mass ABS
1.0% 0.1998 g 19.8001 g

The NH4+-CNC was sonicated from 10:15 am at 26°C to 12:05pm at 36°C. It was sonicated with the ABS added from 12:05 am at 36°C to 3:30pm at 41°C.

The NH4+-CNC was poured into a flask containing 200 mL acetone. The solution was then poured into a blender and mixed at a high setting for 30 seconds to grind up the cellulose so it became a find powder on the bottom of the flask.

While sonicating the ABS, the solution was manually stirred with a glass stirring rod to break up any clumps.

It is important to note that for all castings made are with the Dr. Fox ABS while extruder was flushed with Filabot ABS.

When the 20 g NH4+-CNC sample was removed from the sonicator and added to the pan several lumps of ABS were noted. It was theorized the sample should have been sonicated longer. Another idea was to cut up the pieces of ABS into smaller fragments.
